llpplication filed May 19, 1890. Serial No. 352,382 (No model.)

To all whom it may concern:

Be it known that LHOSMER TUTTLE, a citizen of the United States, residing at Cedar Rapids, in the countyof Linn,State of Iowa, have invented certain new and useful Improvements in Grain-Binders, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to improvements in straw-band grain-binders; and the objects of myimprovement are to producea simple and effective mechanism for tying gavels of grain with straw, as will be hereinafter described, and specifically set forth in the claims. I accomplish these objects by the construction illustrated in the accompanying drawings, in which Figure 1 is a top view of the frame of a grain-binder constructed in accordance with my invention,.the knotter-frame and the binder-platform being removed to clearly show the operating mechanism thereunder. Fig. 1 is a bottom view of the double cranklever of the band-pulling mechanism. Fig. 1 is a top view of the clutch-latch and of the stop and releasing lugs therefor projecting from the side of a'gear-wheel. Fig. 1 is a section of a portion of said gear wheel with the latch-releasinglug in elevation. Fig.

v1 is a side view of the clutch-lever and its latch. Fig. 2 is an end view of the same mechanism and also ofthe knotter-frame and its mechanism. Fig. 2 is a vertical section on line y y of Fig. 1, showing the clutch-1ever and its latch in elevation. Fig. 3 is a transverse'section of the binder-platform, showingthebundle-elevatorinsideview. Fig. 4 is a longitudinal section through the needleshaft and bundle-elevating cam. Fig. 5 is a front view of the central portion of the frame to support the compressors and the needledriving mechanism. Fig. 6 is a side view of the bundle-compressors closed and of the cam to operate the band-pulling mechanism. Fig. 7 is a side View of the compressors shown open and of the cam through which they are operated. Fig. 8 is a top view of the compressors shown open. Fig. 9 is a side view of the inner side of the knotter mechanism. Fig. 10 is a top view of the knotter mechanism. Fig. 11 is a vertical section of the knotter mechanism on line m w of Fig. 9. Fig. 12

is a side view of the outer side of the knotter mechanism. Fig. 13 is a side view of the inner side of the knotter mechanism. Fig. 14 is an end view of a portion of the knotter mechanism. Fig. 15 is a vertical central section of the twister andtucker portions of the knotter mechanism on line y 'g of Fig. 14 and looking in the direction of the arrow in said figure. Fig. 16 is a top view of a circular plate in two unequal parts, the smaller part to be secured to the knotter-box and remain stationary, and the largenpart to be secured to a vertically-movable stud to operate a pivoted finger adapted to enter between the branches of the knotter-fork and hold the band therein while said band is twisted and tucked.

In said drawings, A represents the binderplatform timbers, and A the metal beams of said platform. Said timbers and beams are an improvement upon those shown in my application, Serial No. 278,715, and are secured at one end to the tubular rod A and at the other to the tubular rod A, and to the latter rod are secured the bearings A for the needle-shaft B, which is for convenience made in two lengths united together at their crank end B by the crank-pin 19. One end of the needle-shaft passes through a sleeve B that is retained in boXings in one end of the metal beams A The rod A is secured to the binder-frame by hooks A in the usual manner, and the outer end of the platform is supported by the brace A bearing against the rod A and the brace A bearing against thesleeve B The timbers A and beams A also carry the bearings for the driving-shaft C under said timbers and beams. Upon the end of the driving-shaft is placed a pinion O loosely mounted thereon, and secured to said shaft is a member 0 of a clutch, adapted to engage with a second member on the side of the pinion. This pinion gives motion to a gear-wheel B on the needle-shaft by means of the idler gear-wheel B mounted upon a shaft B having its inner end in a hearing A", projecting laterally from the bottom of the outer beam A and its outer end received in a strap B mounted .upon the ends of the shafts B and O.

The binder is shown in Fig. l withits parts in the position they occupy just after a bundle is ejected. The pinion O is then out of clutch with the driving-shat" t, and the gearwheel B is locked by means of a lug 12', projecting laterally from one of the spokes of said wheel at a short distance from its rim, coming into engagement with the under side of alatch b which is connected with the triplever D; but just before coming into engagement a pin Z2 having its upper surface beveled outwardly and located alongside of the lug 11' between the latter and the rim of the gear-wheel, enters the notch b in the latch 19 and pushes the latter sidewise toward the beam A and as said latch is carried by the clutch-lever d one end of said lever will be pushed toward the beam A while its opposite end, carrying the clutch-fork, will force the pinion C out of clutch toward its operating-spring C and stop the mechanism. The latch 11 is retained on the under side of the lever d by means of two headed pins 'or bolts 1), passing through slots in said lever, the heads of said pins extending beyond the edges of said slots. the top of the bearing A",so that although it can be rocked horizontally it cannot be moved eudwise, and to prevent its outer end from being lifted by the lug b of the Wheel B", pressing under the end of the latch h a lug a projecting from the side of the beam A sustains all the pressure.

To connect the stop-motion or cut otf above described with the trip-lever D, the latter, although located alongsideof the needle, hasone end secured upon a shaft D capable of rocking in its bearings secured to the under side of the beams A Said shaft has a tendency to revolve and keep the outer end of the triplever elevated under the impulse of .a spring D coiled around said shaft and having one end secured thereto and the otherend adjustably retained between a pair of pinsof a circular row projecting from the side of a plate D secured to theside of the beam A and the size of the bundle desired to start the trip can thus be regulated. Upon the outer end of the shaft D is secured a crank-arm D carrying oneend of a connecting-rodDflwhich has its opposite end pivoted to one of the pins b of the latch, so that when a suificient amount of grain is resting upon the trip'lever and depresses it the crank-arm D and rod D push the latch b out of engagement with the lug b of the wheel b and thespring C slides the pinion 0 upon its shaft and maintains its member of the clutch in engagement with its mate and the whole binding mechanism is started and operated until again arrested, as above stated.

Upon the needleshaft alongside of the needle B is secured a crank-arm B to lift the bundle-elevator (1 Fig. 3, at the time that the tuck is made on the ends of the grain-band. The elevator has its inner end pivoted at a IO a lug a pendent from the under side of the binder-platform a. The opposite end of the elevator has a pendent arm a, preferably the needleshaft B.

The lever d is pivoted at d to grooved in the lower end to steady it when in engagement with the crank-arm B The compressor is operated substantially as previously described in an application for patent filed by me September 18, 1889, Serial NO. 324,330, but its supporting means are of different construction. The inner jaw I has its lower end pivoted to the casting H by means of the pin z',-having one of its ends retained in the lug H of said casting and the other end in the body of the casting II; but the outer jaw 1 has its pivot-pin 2' at a point higher than the pivot-pin i. The jaws are operated from the upper end of a lever K, having its lower end pivoted to a lug K projecting from the bottom of the casting ll. To control the upper end of the lever K, it has a roller is, mounted upon a pin projecting from its side, and said roller travels in and is controlled by a cam L, mounted upon The uppcr cnd of. the lever Kis connected with the lower end of the extension of the jaw l by the connecting-rod 1' but the upper end of the lever K is yieldingly connected with the jaw I at a point higher than its pivot 2', so as to render said jaw yielding to receive and operate upon bundles of diiterent sizes. For this purpose there is also pivoted to the upper end of the lever K a connecting-rod i that unites it to one arm of a bell-crank lever 2' and said lever is pivoted to the casting H by means of the pivot-bolt t'. The other arm of the bellcrank lever has its freeend bent laterally toward the jaw I and is yieldingly connected thereto by means of a bolt 2', passing loosely through said bent end and through a lug 1', Fig. 8, projecting laterally from the jaw I, and a spring i placed upon the bolt; i and having one of its ends pressing against the bentendof the bell-cran k lever and the other end against the lug I. The inner jaw I has a tailor guard 1 extending from its point to arrest the grain and prevent it from lodging under the jaw I during'the operation for opening it while the previously made and tied bundle is discharged.

To properly support the compressor mechanism and the needle-operating mechanism, and thus relieve the needle-shaft, the tubular rod A is bent down into U shape about the middle of its length, as shown in Fig. 5, and upon the lower portion of said bent part the lower end of the casting II is mounted and secured. The outer edge of this casting is convex to act as a stripper for the discharger E, secured to the cam L, a casting H of substantially the same form in outline as the casting H, being placed alongside of the second discharger E, secured to the shaft B. To the shaft-supporting castings H and Il are also pivoted the links 6 of the packers T. Between thecastings H and H there is also mounted upon the U-shaped portion of the rodA a cast brace H to support the needleshaft adjacent to the needle and crank upon said shaft and to support the levers of the needle mechanism; but said packers: and needle mechanism form no part of this invention.

To control the band-pulling mechanism, a double crank-lever e is pivoted at 6 Fig. 1, in a sleeve on the under side of the beam A The upper arm of said double crank carries at its upper end a roller to travel in its grooved operating-cam L Figs. 1 and 6, and the lower arm carries at its lower end a connecting-rod a that unites it to the pendent.

arm of a bell-crank lever e ,'that is pivoted loosely upon the driving-shaft (J. The upper arm of said lever carries in suitable bearings a short shaft 6 upon the outer end of which is mounted a wheel e, having cogs or serrations upon its periphery to produce at suitable time the desired friction upon the straw band to advance it, the latter being supported by a roller 6 mounted in a metal frame a suspended from the tubular rod A of the frame. a I

The breast-plate consists of an upper plate F and a lower plate F The plate F is secured to the casting F 'a'ndth'e latter is carried by the U-shaped frame G. The plateF has a slot F extending nearly the whole length thereof, on one side of which there is a point F where another slot diverges therefrom. These partsare-nearly'similar in form, but differ in construction from those shown in the pending application, Serial No; 278,715.

To hold the bundle a suff cient distance from the knotter while the needle-arm is passing the band around the bundle to allowa sufficient amount of slack on the band to make the knot, the lower plate F is used. Said plate is hinged at its inner end to lugs .under the plate F at-f and is longitudinally slotted for the passage of the needle. The outer end of the plate F is controlled by the bundle to elevate it and by roller f to positively depress it in traveling against the periphery of a cam g, projecting from the back of the mutilated gear G which controls all the movements of the knotting mechanism. The roller f is at the end of a connecting-rod f that has its lower end pivoted to a lug f projecting from the outer end of the plate F When the latter is not elevated by the bundle, it drops by its own weight until a lugf on' the side of the rod rests upon the plate vF, as the camg is simply a cam operating by its outer periphery. The roller is retained in proper relation with the cam by means of the brace f having its outer end pivoted to the frame F. 4

To operate the knotter mechanism, one end .of the band is first passed from the bandmaking mechanism through the eye of the needle to the grasper h, Figs. 9 and 11, and

hereinafter described, where the end of the band is retained. The bight of the band is then depressed into the knotter-fork by the flow of the grain, and a sufficient amount being received the eye end of the needle is elevated and encircles the bundle with the band, and as said band is along the inner side of the body of the needle which travels in the slot F the band passes along the inner side of the dividing point F in the plate F. The

band-leading lever Z then pushes the baud between the branches of the knotter-fork is, where it is. retained by the band-holding lever m,'the lower end of which enters between said branches, and then thesecond end of the band being cut and retained by the grasper and the lever m retracted the knotter-fork is swung in a circle to twist the ends of the band together, and afterward swung on its axis, the ends of'the bandare thereby tucked under the band. 7 The band-leading lever Z is located under the plate F and has at one end a stud 1*, that passes through said plate and a boss thereon. Upon said stud is secured an arm Z having at its end a pin that passes through a slot in the bent end of a connecting-rod Z and the opposite end of said rodis pivoted to the lower end of a lever Z Said lever is pivoted to the cast frame F3 at Z Fig. 2, and has at its up per end a roller (not shown) to travel in the cam G mounted upon the shaft G of the knotter mechanism, and said shaft carries a sprocket wheel L around which passes a chain L that passes also around a sprocketwheel L upon the needle-shaft, from which to receive its motion.

Thelband grasper and cutter consist of a post k projecting up from the plate F and carrying a stationary blade alongside thereof, and the'horizontally-reciprocating grasper h, carrying a blade. (Shown by the serrated edge in Fig. 11.) Said grasper has pivoted to its top at h one end of a lever 71 that is pivoted at h -to a lug f projecting from the cast frame F and the opposite end of said lever has a roller to travel in its operatingcam- G on'the face of the mutilated gear G so that the grasper is operated by said lever k and its cam G Said gear has a segmental outer row of cogs G and has an inner row G and alongside of said cam are mounted two pinions M and M to rotate the knotter-fork 7c first in a circle and then upon its own axis. Said pinions have their shafts retained in a knotter-box F connected by an arm F and also an arm F with the cast frame F 5 The pinion M is pinned to one end of the central shaft M of the knotter, and the opposite end of said shaft carries pinned thereto the frame M in which bearings are provided for the shaft of the knotter-fork and its operating-gears. The twister consists of the frame M Figs. 12, 13, and 15, that is suspended from the lower end of the shaft M and the latter is carried bythe knotter-box F upon which the pinions M and M rest. Immediately-after the band-holding lever m has entered between the branches of the knotterfork the double row of cogs on the face of the mutilated gear begins to engage with the two pinions M M of the knotter and revolve them in the same direction and with the same speed and cause the knotter-fork to revolve on its own axis and wind the ends of the band around it about one turn and a half, and also cause said knotter-fork to revolve in a horizontal circle. After the end of the seg ment of teeth (3% has been reached the pinion M continues to revolve on account of its ongagement with the longer segment of teeth G upon the mutilated gear; but the pinion M remains stationary, and this causes the knotter-fork to revolve upon itsown axis and form the tuck of the knot under the band. The blank space left at G between the end of the segment G and the small segment of teeth G is to give time for the bundle to be discharged from the knotter-fork by the dischargers, and the small segment of teeth G is to revolve the knotter-fork in a circle to the position it must occupy to receive a new band.

To cause the knotter-fork to occupy a position on the axis of a line passing through the center of the shaft M of the kuotter, so that the center of the knotter-fork will swing around on said axis and produce an equal strain upon both ends of the grain-band, the frame M is extended on one side of the axis of the shaft M and a revolving motion is given to the axle of the knotter-fork, as follows: The pinion M is secured to the upper end of a sleeve M, having upon its lower end a bevel-pinion M, which meshes with a pinion ll 7 upon a shaft M in a bearing in the frame M and said shaft carries on its outer end a gear-wheel N, which meshes with a similar gear N upon the shaft of the knotterfork. These gears are inclosed in the frame M by a cap-plate N secured to said frame.

To cause the lowercnd of the band-holding lever m to be tipped down into the knotterfork, its upper end is pivoted to the frame M atm and carries pivoted thereto at m a link 972*, having on one side a recessed groove m to receive the enlarged edge of a segment 19 of a ring. Said segment is a little more than a half-circle and has a central segmental perforation to fit loosely around the knotter-box F The segment 1) is carried vertically up and down by a stud p integral therewith, but recessed at its lower end to permit the passage of the head of the link m around the edge of the segment 1). The stud p is guided in a perforation made vertically in a lug F, Fig. 14:, projecting from the side of the knotterbox. To reciprocate the stud p vertically, a lever q is pivoted at (1 to the lug F and has its upper end provided with a roller to travel in the groove or against a cam Q on the back of the mutilated gear, the leverq being united to the stud p" by means of a connecting-link g To complete the segmentp and form therewith a ring for the link m to travel upon and rotate with the knotter when the lower end of the holding-lever mis in engagement with i the knotter-fork, a second segment 19 is secured to the bottom of the knotter-box or made integral therewith,so that when the segnient p is lowered tothe level of the segment 13 a complete circular track is produced to guide the link on and retain the lower end m of the band-holding lever in the knottcr-fork while the ends of said band are twisted together and tucked under the band.

To permit the kuotting mechanism to be swung in a circle in the large opening formed in the breast-plate F, but at the same time permit the point F in said plate to guide the grain-band to the knotter-fork, a latch 1' is pivoted at r to said breast-plate and adapted to swing horizontally out of the way when the casing of the gears N N of the knotter strikes against it, and the latch is returned to normal position by the grain-baud sliding against the point F and against the outer edge of said latch on its way to the kn'otter-fork.

The frame to support the frame F, carrying the breast-plate,tl1e knotting mechanism, and its driving-shaft G consists,mainly, of three wroughtiron tubes G and two horizontal tubes G. The lower ends of the tube G are inserted in sockets in the large sleeve end A of the outer beam A and have their upper ends inserted in webbed elbows S, which are provided on one side with a bracket (shown by a dotted segment of a circle in Fig. 2) to support one end of the shaft G. In said elbows is also inserted in a horizontal position one end of the tube G, while the opposite end is secured in tubular sockets F projecting from the inner side of the breastplate carrying frame F.
